Actually, in a strange sort of way, he’s displaying a small streak of cleverness.
Clearly Sanders understands at some level that his core constituency is made up almost exclusively of people who are dumber than a box of rocks. After all, he needs to rope in a whole lot of Obama voters, and we all know that most Obama voters have IQs roughly similar to their shoe size. So he knows instinctively that whatever BS he dishes out, they’ll lap it up as if it were chocolate.
Ya know, youre right on target. His ads here are completely directed to the ‘dumber than a rock’ type. Theyre short and very convincing if you dont bother to think (even a little). Im pretty sure he’s going to do very well on primary day.
Given this its hard to imagine a group dull enough to send Burnie to DC even once. However, the eletorate of VT did that and much more.
